Title:
VECTORIZATION PROCESSING SYSTEM
Document Type and Number:
Japanese Patent JPH04286071
Kind Code:
A
Abstract:
PURPOSE: To shorten the execution speed of a program by vectoring a recurrence formula including division.
CONSTITUTION: When a recognition means 21 in a compiler 2 reads a source program 1, and the recurrence formula including division appears in a loop, the loop is fetched and transferred to a next deformation means 22. The deformation means 22 unrolls the two stages of the loop and substitutes the same arrangement of the left side of a first stage in the sentence of a second stage for the right side of the sentence of the first stage. Then, the sentences of the second stage and the first stage are exchanged. A code generation means 23 generates a target program 3 at last.
